From my daily devotional book:
God is God. Because He is God, He is worthy of my trust and obedience. I will find rest nowhere but in His holy will, a will that is unspeakably beyond my largest notions of what He is up to (Elisabeth Elliot)
Key Scripture: Deuteronomy 30:2-3 ~ note the use of the word "when" throughout this section of scripture. This tells me that these are PROMISES to rest on.
